KNIFE ATTACHMENT FOR LINOTYPE-MACl-llNES.

SPECIFICATION forming part of Letters Patent 0. 609,315, dated August16, 1898.

Application filed October 1, 189 6 To a, whom it may concern.-

Be it known that I, TVATKIN WYNNE, journalist, a subject of the Queen ofGreat Britain, residing at Bon Accord avenue, WVaverly, near Sydney, inthe British Colony of New South \Vales, have invented new and usefulImprovements in Two-Line-Letter Knife Attachments for Linotype-Machines,of which the following is a specification.

This invention relates to those attachments for linotype-machines whichplane or dress the linotypes or slugs as they are ejected from the moldin the casting-wheel, and which consist of knives or planing edgespresented to the advancing slug as it is ejected into the stick andwhich are commonly termed knife attachments; and this invention refersto those kinds of such attachments which will plane or dress linotypesor slugs having two-lineletters protruding or overhanging beyond theirbodies.

This invention has been specially devised in order that the knifeattachments will plane or dress the full length of the linotype or slugand with but slight and facile regulation or manipulation will likewiseallow the passage of slugs having thereon overhanging two-line lettersand, if necessary, plane or, dress the edge of the overhang parallel tothe body of the slug.

These improvements in two line letter knife attachments forlinotype-machines consist,essentially,in the peculiar construction ofthe knife, having part of its knife-edge adapted (under the necessaryregulation) to have motion transversely of the cutting edge,so that saidknife-edge may be continuous when it is to plane or dress aparallel slugor may be noncontinuous when a slug with an overhanging two-line letteris to pass or may be noncontinuous but have a subsidiary parallel cutting edge at the gap when a slu g and its overhanging two-line letterhas to be dressed as it is passing onward; and these improvementsconsist, further, in the particular combinations and arrangements ofparts hereinafter described and claimed but in order that this inventionmay be clearlyunderstood reference will now be made to the drawingsherewith, in which- Figure l is an internal face View of a knifeattachment for a linotype-machine having Serial No. 607,574. (No model.)

these present improvements embodied there in. Fig. 2 is an edge view,and Fig. 3 is a perspective view, of the same; and Fig. 4 is across-section of'the whole through gapknife.

In order to the better understanding of these improvements, the wholeknife attachment (one side of the set) is shown; but for the purposes ofthis specification there is no necessity to refer to those parts inwhich no alteration is necessary to the carrying out of this invention.

Transversely through the knife-body A and the edge A a slot or bed B iscut or made, which may have parallel sides, but is preferably ofdovetail shape, as shown, so'that there will be a gap in the cuttingedge A. a In this slot or bed B, exactly fitting the same and adapted toslide to and fro therein, is the gap-knife 0, having cutting edge C. Thebody of this gap-knife O is seated in the gap of the main knife'A, andthe cutting edge 0 of said gapknife is coincident with the cutting edgeA of the main knife when the gap-knife is adjusted to its forwardposition, so that a continuous cutting edge from end to end of the mainknife A is provided. This gap-knife may be of any approved cross-sectionso long as it will slide in the bed 13 and its edge 0 will fit exactlythe gap in the edge A; but it is preferably of the same cross-section asthe removed part of the body A. The to-and-fro mot-ion of this gap-knife0 will enable the edges A and O to be made continuous or to enable theedge A to have the gap (through which the overhanging two-line lettermay pass) and to enable the edge 0 to plane or dress the bottom edge ofan overhanging twoline letter.

The transverse to-and-fro motion of the gap-knife C may be imparted toit by many mechanisms so long as the travel and movement is under easycontrol. The best devicesnow known for such purpose are as fola,

volved, so as to operate eccentric D and so advance or withdraw thegap-knife .O for the purposes before mentioned. Bolted at E to thesleeve-bracket D is a quadrant or seetor E, to which may be screwed ateither end or to either of the series of holes through an oval hole thestop-pieces E by which the movement of the handle may be checkedaccording to the predetermined adjustment of said stop-pieces, as willbe clearly seen, and so that the scope of the movement of the gap edge 0may be regulated.

Having now particularly described and ascertained the nature of my saidinvention and in'what manner the same is to be performed, I declare thatwhat I claim is In two-line-letter knife attachments for
